Yes. An example is Roxas can use "Two Become One", which is "Oathkeeper" and "Oblivion" put together in one Keyblade.
Oblvian and Oathkeeper, those are Roxas' keyblades (Oblivian being his darkness, Oathkeeper being his light)
Oblivion is the black one, Oathkeeper is the white one.
it is not impossible but you have to ask another website buddy
Soul Eater Sora's Kingdom Key Keyblade of People's Hearts Roxas's Oblivion Way to the Dawn Destiny's Embrace
Roxas first appears in Kingdom Hearts II.
Roxas does not appear in Birth By Sleep. There is Ventus, who looks like Roxas, but is very different than Roxas.
As Axel explained to Roxas, Heartless that are destroyed not by the Keyblade regenerate back into Heartless. However, the Keyblade has the power to release the hearts to Kingdom Hearts.
Roxas is Sora's Nobody.
Purchase Zero Gear 5 weapon panel and link three ability units (L). Roxas will then hold two keyblades in mission mode.
In Kingdom Hearts II, you can only fight Roxas in Kingdom Hearts II Final Mix, which is only available in Japan.You fight Roxas after Axel's death scene, where you are in The World That Never Was, next to the skyscraper.A cutscene will activate, and Samurais will surround Sora, preventing Donald and Goofy from joining the fight. Sora will then be in his own thoughts (or something along those lines), and Roxas will be hooded, wielding his dual keyblades. Then the battle will take place. This is the modified version of Roxas and Sora's cutscene fight in the original game of Kingdom Hearts II.
No, you cannot. There is a point in the beginning of Kingdom Hearts II, however, when you fight a boss with dual keyblades. You play as Roxas in The Mansion's basement, and you fight Axel, an Organization XIII member. You can also fight with dual keyblades when in Wisdom, Valor, Master, or Final Form as Sora (also in Kingdom Hearts II).
roxas is the nobody of sora, originated after sora released his heart in Kingdom Hearts I
